今天初始Quartz2D,我好激动啊,也好开心,莫名的会喜欢带有图形相关的课程……
好啦,闲话少说,今天用Quartz2D方法画了最最爱的大白。迫不及待的想要和大家分享。
1、首先实例化了view
2、在实例化的view的写代码就可以了,是不是很简单。
//不允许直接调用drawRect方法,使用setNeedsDisplay 间接调用drawRect方法
- (void)drawRect:(CGRect)rect {
//获得图形上下文
//获得当前图形上下文
CGContextRef context = UIGraphicsGetCurrentContext();
//头
[self drawHeader:context];
[self drawHeader2:context];
//眼睛
[self drawEye:context];
[self drawEye2:context];
[self drawEye3:context];
[self drawEye4:context];
[self drawEyeLine:context];
//身体
[self drawBody:context];
[self drawBody2:context];
[self drawBody3:context];
[self drawBody4:context];
[self drawBody5:context];
//脚
[self drawBody6:context];
[self drawBody7:context];
}
#pragma mark 画头(上边)
- (void)drawHeader :(CGContextRef) context{
// 1. 圆心 ,半径,起始和终止角度 ,方向
CGContextAddArc(context, self.frame.size.width/2, 150, 50, 0,- M_PI, 1);
CGContextStrokePath(context);
}
#pragma mark 画头(下边)
- (void)drawHeader2 :(CGContextRef) context{
// 1. 圆心 ,半径,起始和终止角度 ,方向
CGContextAddArc(context, self.frame.size.width/2, 150, 50, 0,- M_PI, 0);
CGContextStrokePath(context);
}
#pragma mark 眼睛(左下)
-(void)drawEye:(CGContextRef) context{
CGContextAddArc(context, 162, 160, 10, 0,- M_PI, 0);

}
#pragma mark 眼睛(左上)

}
#pragma mark 眼睛连线
- (void)drawEyeLine :(CGContextRef) context{
//移动到某一点
CGContextMoveToPoint(context, 162, 160);
//添加一条线
CGContextAddLineToPoint(context, 212, 160);
CGContextSetLineWidth(context, 3);//线宽
// 3.绘制图形
CGContextStrokePath(context);

原谅小菜鸟见得世面少,不过,真的有认真地写了代码,请喜欢大白的童鞋,拿去试试吧,大白送给你们。
今天学习很开心,明天继续加油,大家一起加油哟~~
